#	   --target=TARGET	specifies target configuration.
#	   --build=TARGET	specifies configuration of machine you are
#				using to compile GCC.
#	   --prefix=DIR		specifies directory to install in.
#	   --local-prefix=DIR	specifies directory to put local ./include in.
#	   --gxx-include-dir=DIR specifies directory to put g++ header files in.
#	   --exec-prefix=DIR	specifies directory to install executables in.
#	   --with-gnu-ld	arrange to work with GNU ld.
#	   --with-gnu-as	arrange to work with GAS.
#	   --with-stabs		arrange to use stabs instead of host debug format.

#	   --nfp		assume system has no FPU.
#
# If configure succeeds, it leaves its status in config.status.
